| Abstract(in English) | In ad hoc networks, since each terminal transmits data using radio devices, link failure or segment loss frequently occurs owing to interferences or obstacles. If TCP Reno is used in ad hoc networks, the congestion window size shirnks into half to avoid congestion when segment losses are observed. However, segment losses are caused by not only congestion but also interference and obstacles. Thus, unnecessary window size shrink is invoked and this decreases the end-to-end throughput. As concerns this, TCP Westwood that uses bandwidth estimation for window size shrink and TCP Vegas that uses expected and measured throughput for flow control are proposed. This paper proposes a novel flow control method using the round trip time and the method for reducing redundant segment retransmission. The performance and effectiveness of the proposed method is clarified by computer simulation. |
